Stacking cup cap

ABSTRACT

A stacking cup cap aims to cover a cup body which includes a cup top rim and a cup bottom side. The stacking cup cap includes a closing cap anchored on the cup top rim, a sealing lid connected to the closing cap and remote from the cup top rim and a drinking orifice. The sealing lid includes an indented stacking space to hold another cup body. The cup bottom side of another cup body is formed at a size mating the stacking space. The drinking orifice is located on the sealing lid corresponding to the stacking space to be covered by another cup body. Thus, through the stacking space a plurality of cup bodies can be stacked over one another at greater stability. After stacking the drinking orifice does not form direct communication with the exterior, hence can resolve the problem of dust contamination.

FIELD OF THE INVENTION

The present invention relates to a cup cap and particularly to a stacking cup cap.

BACKGROUND OF THE INVENTION

Disposable beverage cup is one of handy items used frequently by many people nowadays. Taiwan patent No. M446764 disclosed a “One time usage cup cap for two people” which includes a cup cap, a cup opening located on the cup cap and a concentric recess for stacking other paper cups. The cup opening is located outside the concentric recess at an edge of the cup cap. After beverage is filled in a cup, the cup cap can be added for sealing. However, its cup opening is open and communicates with the exterior, and the beverage cup is not fully isolated from the exterior. Dust easily drops into the beverage cup that creates annoying problems to users. In addition, in the event that a user buys multiple servings of beverage multiple beverage cups and cup caps have to be stacked over one another to facilitate carrying by the user. The up and down stacking areas are constrained by the cup opening position, hence the concentric recess has to be shrunk in size. As a result, the multiple beverage cups that stack over one another are unstable and prone to toppling down.

Taiwan patent No. M333128 entitled “Cup cap safety latch structure” proposed a design that includes a movable element, a broken folding line around the movable element and a latch element. The movable element can be pushed to anchor on the latch element to form a drinking orifice usable by users during drinking. Such a design also can avoid direct communication with the exterior and prevent dust from dropping inside. But its cup cap surface for stacking other beverage cups is even smaller than that of M446764 mentioned above. Moreover, when a plurality of beverage cups are stacked over one another the pouch that holds the beverage cups could be easily swayed or incidental impact by users could take place that could incidentally open the movable element that originally covers the drinking orifice. As a result, when the cups are sent to users' hands the dislocated movable element could make users wondering whether the beverage contained in the cup was already being consumed. This could create unnecessary concerns.

SUMMARY OF THE INVENTION

The primary object of the present invention is to solve the problems of the conventional beverage cups of deficiency in stacking stability and ineffective isolation of the drinking orifice with the exterior that results in easy dust contamination.

To achieve the foregoing object the present invention aims to provide a stacking cup cap to cover a cup body. The cup body includes a cup top rim with a cup opening formed thereon and a cup bottom side remote from the cup opening. The stacking cup cap includes a closing cap anchored on the cup top rim, a sealing lid connected to the closing cap and remote from the cup top rim and a drinking orifice. The sealing lid includes a top holding portion corresponding to the cup bottom side in shape, an annular connection portion surrounded the top holding portion and connected to the closing cap, and a lateral detent wall to bridge the top holding portion and the annular connection portion. The lateral detent wall and the top holding portion jointly form an indented stacking space. The drinking orifice is located on the top holding portion. The stacking space can hold another cup body with the cup bottom side thereof mating the stacking space and the drinking orifice covered by another cup body.

Through the structure set forth above, the invention can provide advantageous features as follows:

1. With the drinking orifice located on the top holding portion the stacking space formed on the sealing lid can be maximized in area to enhance stacking stability of the cup.

2. When a plurality of cup bodies are stacked over one another the drinking orifice is covered by another cup body, hence can reduce contact of the drinking orifice with the exterior to reduce the problem of dust dropping into the cup body.

The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown in FIGS. 1, 2 and 3, the present invention aims to provide a stacking cup cap to cover a cup body 10. The cup body 10 includes a cup top rim 12 with a cup opening 11 formed thereon and a cup bottom side 13 remote from the cup opening 11. The stacking cup cap includes closing cap 20 anchored on the cup top rim 12, a sealing lid 30 connected to the closing cap 20 and remote from the cup top rim 12 and a drinking orifice 40. The sealing lid 30 includes a top holding portion 31 formed in a shape corresponding to the cup bottom side 13, an annular connection portion 32 surrounded the top holding portion 31 and connected to the closing cap 20, and a lateral detent wall 33 to bridge the top holding portion 31 and the annular connection portion 32. The lateral detent wall 33 and the top holding portion 31 jointly form an indented stacking space 34. It is to be noted that the top holding portion 31 mates the shape of the cup bottom side 13 and is formed in a circular shape. Of course, other types of shape also can be adopted, such as square, ellipse or the like.

In addition, in this embodiment the annular connection portion 32 can include an upper annular connection wall 321 connected to the lateral detent wall 33 and a lateral annular connection wall 322 to bridge the closing cap 20 and the upper annular connection wall 321. The upper annular connection wall 321 is spaced from the cup body 10 at a distance greater than that of the top holding portion 31, thereby forms an elevation difference with the top holding portion 31, also allows the lateral detent wall 33 and the top holding portion 31 to form the stacking space 34. It also to be noted that, in this embodiment the annular connection portion 32 includes a drinking aid recess 323 corresponding to the drinking orifice 40 to aid users to drink the beverage contained in the cup body 10 in a more desirable contact manner. Furthermore, the upper annular connection wall 321 and the top holding portion 31 are spaced from each other at a distance preferably smaller than 5 mm to make stacking more stable and also to shrink the space of the cup cap.

The drinking orifice 40 is located on the top holding portion 31 inside the lateral detent wall 33, therefore the stacking space 34 is not affected by the drinking orifice 40 and can be designed by extending outward from the circular center at a greater area, namely the lateral detent wall 33 can be formed closer toward the closing cap 20 to make the stacking space 34 bigger in size, therefore the cup body 10 can be stacked on a bigger area in a more stable fashion. In this embodiment the top holding portion 31 further includes a butting member 50, a punch section 311 encircled the butting member 50 and a connection section 312. The butting member 50 includes an initial position and a drinking port position in which the punch section 311 is severed under pressure and bent toward the connection section 312 to form the drinking orifice 40. In addition, in this embodiment the punch section 311 is located at a location where the butting member 50 is abutting the center of the sealing lid 30. The top holding portion 31 further includes a latch trough 313 at one side of the connection section 312 remote from the butting member 50. Therefore, at the drinking port position the butting member 50 can be latched without subject to the bouncing back force of the connection section 312 to cover the drinking orifice 40.

As shown in FIGS. 4 and 5, the stacking space 34 aims to hold another cup body 10 a with the cup bottom side 13 a thereof formed at a size mating the stacking space 34, and also with the drinking orifice 40 covered by the another cup body 10 a. As shown in FIG. 5, when two or more cup bodies 10 are stacked incorporating with the cup caps, the drinking orifice 40 is fully covered by the cup body 10 a at the upper side, hence unnecessary external impact to the butting member 50 can be avoided to prevent the punch section 311 from being severed before use that might otherwise cause troubles to users.

As a conclusion, the invention can provide features as follows: 1. By forming the drinking orifice on the top holding portion the stacking space is not affected by the drinking orifice, and the stacking space on the sealing lid can be maximized in area to make stacking of the cups more stable; 2. When a plurality of cup bodies are stacked over one another the drinking orifice is covered by another cup body, thereby contact of the drinking orifice with the exterior can be reduced, and the problem of dust dropping into the cup body also can be alleviated; 3. When the cups are stacked over one another the butting member and the drinking orifice are covered by the cup bottom side of another cup body, hence impact by external forces can be avoided and incidental severing of the punch section also can be prevented, and troubles to the users that might otherwise occur also can be averted. In short, the present invention can provide significant improvements over the conventional techniques.
